Their driving duo of Max Verstappen and Sergio Perez have amassed 301 points after the first nine races of the season, and look well on course to secure a third consecutive title.
Reigning world champion, Verstappen, has clinched victory in all but three races in 2024, but the Dutchman has looked some way off his imperious best.
In an interview with OE24, Red Bull chief Marko said the plan to announce the deal despite Perez's difficulties was intended to settle the team, but hasn't quite turned out that way.
The 81-year-old, however, has backed the six-time race winner to show what he can do over the upcoming races ahead of the summer break.
"We extended his contract because we wanted to bring calm to our team, which unfortunately didn't quite work out," said the Austrian.
"But now Checo has three races ahead of him on three real race tracks, so he can prove himself."
